This program is designed to calculate probabilities when using a dice pool.
Dice pools are used in role playing games such as Shadowrun, Star Trek, the Storyteller games, and other games. A dice pool is used by rolling a number of dice and, rather than adding them together, comparing the rolls to a target number and counting how many dice meet that target.
Here are the figures (non-cumulative) for 2 20-sided dice rolled against a target number of 16:
The probability of 2 successes is 6.25
The probability of 1 success is 37.5
The probability of no successes is 56.25
and here is the form itself:
